SIEPMANN GROUP

Customer in focusOur customers are market leading technology companies and are active in all important international industrial

markets. They value stable long-term supplier relationships, short delivery times, high quality products, efficient

solutions and flexibility, both in daily business activities and for new developments.

Technology within the networkOur products are sophisticated die forgings, hot extrusions and industrial valves made from steel. We use

state-of-the-art processes to develop and manufacture our products. Our integrated technological skills with

forging technology, heat treatment, metallurgy, machining, module assembly and diverse welding processes,

including electron beam welding, make us unique in the industry.

9003.1.01.15 1

Dedicated employeesOur employees are part of our success story. Our staff, of over 500, includes cases of several generations of the

same family. Every employee takes responsibility for the company‘s success and is encouraged and empowered

to make decisions that will benefit both the company and our customers. Our specialists apply their technological,

industrial and product expertise to ensure outstanding customer service.

Successful family enterpriseOur core competences, from the beginning, have been the development, production and marketing of sophisticated

customer specific steel product solutions. As an independent family run business for almost 125 years, and now in

the fourth generation, we are one of Europe‘s leading industrial companies with an annual turnover of 100 million

Euros and a global network of sales representatives.

The family business started as a die forge in 1891 and was run by the brothers Emil and Hugo Siepmann. Emil and

Hugo subsequently bought out their brother-in-law and shareholder, Louis Peters. In 1946 Stahl-Armaturen

PERSTA GmbH was founded with the aim of manufacturing and marketing high-pressure steel valves for industrial

applications. Thanks to the reputation and support of the SIEPMANN forge, PERSTA was soon a successful

supplier of steel technology. VALTRA GmbH was created in 1980 as a trading company to supply valves from

other manufactures. This enabled us to offer our customers complete solutions for all their valve requirements.

Under the leadership of the third generation of the family, the future course was set by investments in highly

automated CNC machining technology and a cutting edge automated die forging technique. The technology

strategy was completed with the purchase of a majority shareholding in SD MACHINING GmbH in 2011,

a company specialising in mechanical processing. Today‘s fourth generation of the family represents the

sustainability and enhanced customer orientation of the SIEPMANN GROUP. An active change management

programme was implemented to respond to the technical and commercial demands of our customers.

Die Forging SIEPMANN GROUP has invested extensively in comprehensive process automation and manufacturing solutions

for sophisticated forged parts. Our investment programme together with our consistent adherence to exceptional

quality principles are driving growth in the die forging division. Our processes for die forging, hot extrusion, welding

and mechanical processing are constantly being further developed using modern technologies.

We apply the highest standards of quality in the production of die forged and hot extruded parts ranging in weight

from 5 to 1500 kg. Flexibility is one of our strengths. It enables us to offer small and medium sized production

quantities in a wide range of shapes and steel grades based on customer needs. We offer our customers a

development partner service in which we deliver support in product development (simultaneous engineering),

material selection, mechanical processing and series production.

Our die forging production processes are:

- Die forging

- Hot extrusion

- Heating

- Welding

- Mechanical processing

9003.1.01.15 5

9003.1.01.156

Production methods Our production processes meet the highest quality standards, enabling us to comply with the most demanding

requirements of our customers. We provide support and advice starting with material selection and extending to

the cost-effective design of the forged part. Our modern heat treatment techniques guarantee the best possible

match to our customer’s requirements. This is also illustrated by the more than 250 different steel types across

all quality grades included in our materials list.

Mechanical processingOur division for mechanical processing, SD MACHINING, produces components with a diameter of up to 1300 mm,

a height of up to 500 mm and having a unit weight of up to 2 tons. This capability forms an outstanding base for

us to fulfil all relevant customer and application requirements. With our vertical integration of competencies we are

able to develop tailor-made solutions from pure parts delivery to a system supplier role.

Welding technology and assemblyWelding is a core competence of our industrial valve division PERSTA and we offer a wide range of welded

components. Our investment in modern welding techniques and many years of experience enable us to

contribute positively at the value added stage of any design.

Industrial Valve Division With PERSTA the SIEPMANN company created a successful branch for the development, construction and

fabrication of valves made from steel. Modern equipment and comprehensive approvals in accordance with

international standards guarantee high-quality products and flexible compliance with customer requirements.

Technical developments in terms of pressure, temperature and tolerance call for highly stable materials with a

dense, homogenous structure. The company’s core business consists in the development, production and

distribution of high-quality industrial forged steel valves, variously augmented by valves made from hot-formed

sheets and cast steel. PERSTA steel valves are distinguished by their high quality and reliability.

PERSTA’s high quality products, continuous innovation and business flexibility have helped us become a sought

after specialist for valves, gate valves and check valves. Today we have more than 50 distribution partners around

the world. Application areas for our products include: plant engineering, pipe laying, boiler construction, chemical

and petrochemical industries, conventional and nuclear power plants.

Our PERSTA valve production processes are:

- Die forging

- Automated welding

The processing is performed using:

- CNC machines

- Processing centers

- Flexible production systems

9003.1.01.15 9

9003.1.01.1510

Products

The PERSTA product range comprises pipeline valves and components made from forged steel, cast steel and

hot-formed sheet steel in nominal widths from DN 10 to DN 1000 and pressure classes from PN 10 to PN 630.

Our products are available in standard designs as well as custom designs. Pipeline components made from

die-forged steel provide certain benefits no other manufacturing processes can match, in particular where the

parts of the valve’s pressure housing are concerned, such as the casing and casing cover, and the shut-off

system. Our products are manufactured using the latest technologies. As a successful valve supplier, PERSTA

is of course also able to manufacture parts in compliance with complex customer specifications, according to

DIN-, EN-, ASME- and Gost standards.
